Anatolius of Laodicea (early 3rd century – July 3, 283), also known as Anatolios of Alexandria , became Bishop of Laodicea on the Mediterranean coast of Roman Syria in AD 268. He was not only one of the foremost scholars of his day in the physical sciences as well as in Aristotelean philosophy but also a great computist: Around AD 260 he invented the very first Metonic 19-year lunar cycle (based on the Metonic cycle). Therefore Anatolius can be considered to be the founder of the new Alexandrian computus paschalis which half a century after began with the active construction of the second version of the Metonic 19-year lunar cycle and ultimately would prevail throughout Christendom for a long time (until the year 1582, when the Julian calendar was replaced with the Gregorian calendar). The seventeen centuries old enigma of his famous 19-year Paschal cycle was recently completely resolved by the Irish scholars Daniel Mc Carthy and Aidan Breen. Between Anatolius’ 19-year lunar cycle and the (ultimately chosen) classical Alexandrian 19-year lunar cycle there exists a gap of 2 days which dates from before the first council of Nicaea.
Anatolius is considered a saint by the Eastern Orthodox and the Roman Catholic Churches
Anatolius was born and raised in Alexandria, Egypt, during the early 3rd century. Prior to becoming one of the great lights of the Church, Anatolius enjoyed considerable prestige at Alexandria. According to Eusebius of Caesarea, he was credited with a rich knowledge of arithmetic, geometry, physics, rhetoric, dialectic, and astronomy.Also according to Eusebius, Anatolius was deemed worthy to maintain the school of the Aristotelian succession in Alexandria. The pagan philosopher Iamblichus studied among his disciples for a short time.
There are fragments of ten books on arithmetic written by him. There is also a treatise on time of the Paschal celebration. His famous Paschal cycle has survived in seven different complete medieval manuscripts of the Latin text De ratione paschali.
A story is told by Eusebius of the way in which Anatolius broke up a rebellion in a part of Alexandria known then as Bruchium. It was held by the forces of Zenobia, and being strictly beleaguered by the Romans was in a state of starvation. Anatolius, who was living in Bruchium at the time, made arrangements with the besiegers to receive all the women and children, as well as the old and infirm, continuing at the same time to let as many as wished profit by the means of escaping. It broke up the defence and the rebels surrendered.
In going to Laodicea he was seized by the people and made bishop. Whether his friend Eusebius had died, or whether they both occupied the see together, is a matter of much discussion. The question is treated at length in the Bollandists.
St Anatolius' feast day, like that of his namesake Saint Anatolius of Constantinople, is celebrated on July 3.
Easter, also called Pascha or Resurrection Sunday, is a festival and holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day after his burial following his crucifixion by the Romans at Calvary c. 30 AD. It is the culmination of the Passion of Jesus, preceded by Lent, a 40-day period of fasting, prayer, and penance.
The First Council of Nicaea was a council of Christian bishops convened in the Bithynian city of Nicaea by the Roman Emperor Constantine I in AD 325.
In the Synod of Whitby in 664, King Oswiu of Northumbria ruled that his kingdom would calculate Easter and observe the monastic tonsure according to the customs of Rome rather than the customs practised by Irish monks at Iona and its satellite institutions. The synod was summoned at Hilda's double monastery of Streonshalh (Streanæshalch), later called Whitby Abbey.
Dionysius Exiguus was a 6th-century monk born in Scythia Minor. He was a member of a community of Scythian monks concentrated in Tomis, the major city of Scythia Minor. Dionysius is best known as the inventor of the Anno Domini (AD) era, which is used to number the years of both the Gregorian calendar and the (Christianised) Julian calendar. Almost all churches adopted his computus (calculation) for the dates of Easter.
The Patriarch of Alexandria is the archbishop of Alexandria, Egypt. Historically, this office has included the designation "pope".
The computus is a calculation that determines the calendar date of Easter. Because the date is based on an ecclesiastical or paschal "equinox" date rather than the actual astronomical equinox, there are differences between calculations done according to the Julian calendar and the modern Gregorian calendar. The name has been used for this procedure since the early Middle Ages, as it was considered the most important computation of the age.
Saint Anatolius was a Patriarch of Constantinople.
The epact used to be described by medieval computists as the age of the Moon in days on 22 March; in the newer Gregorian calendar, however, the epact is reckoned as the age of the ecclesiastical moon on 1 January. Its principal use is in determining the date of Easter by computistical methods. It varies from year to year, because of the difference between the solar year of 365–366 days and the lunar year of 354–355 days.
Quartodecimanism refers to the custom of early Christians celebrating Passover beginning with the eve of the 14th day of Nisan.
The Ethiopian calendar or Eritrean calendar is the principal calendar used in Ethiopia and also serves as the liturgical year for Christians in Eritrea and Ethiopia belonging to the Eritrean Orthodox Tewahedo Church, Ethiopian Orthodox Tewahedo Church, Eastern Catholic Churches, the Coptic Orthodox Church of Alexandria, and P'ent'ay Churches. The Ethiopian calendar is a solar calendar which in turn derives from the Egyptian calendar, but like the Julian calendar, it adds a leap day every four years without exception, and begins the year on August 29 or August 30 in the Julian calendar. A gap of seven to eight years between the Ethiopian and Gregorian calendars results from an alternative calculation in determining the date of the Annunciation.
The Buddhist calendar is a set of lunisolar calendars primarily used in mainland Southeast Asian countries of Cambodia, Laos, Myanmar and Thailand as well as in Sri Lanka and Chinese populations of Malaysia and Singapore for religious or official occasions. While the calendars share a common lineage, they also have minor but important variations such as intercalation schedules, month names and numbering, use of cycles, etc. In Thailand, the name Buddhist Era is a year numbering system shared by the traditional Thai lunisolar calendar and by the Thai solar calendar.
The Era of the Martyrs, also known as the Diocletian era, is a method of numbering years used by the Church of Alexandria beginning in the 4th century AD and by the Coptic Orthodox Church of Alexandria from the 5th century to the present. Western Christians were aware of it but did not use it. It was named for the Roman Emperor Diocletian who instigated the last major persecution against Christians in the Empire. Diocletian began his reign 20 November 284 during the Alexandrian year that began on 1 Thoth, the Egyptian New Year, or 29 August 284, so that date was used as the epoch: year one of the Diocletian era began on that date. This era was used to number the year in Easter tables produced by the Church of Alexandria.
Anno Mundi, abbreviated as AM, or Year After Creation, is a calendar era based on the biblical accounts of the creation of the world and subsequent history. Two such calendar eras have seen notable use historically:
The controversy over the correct date for Easter began in Early Christianity as early as the 2nd century AD. Discussion and disagreement over the best method of computing the date of Easter Sunday has been ongoing and unresolved for centuries. Different Christian denominations continue to celebrate Easter on different dates, with Eastern and Western Christian churches being a notable example.
In the year 616 an anonymous scholar extended Dionysius Exiguus' Easter table to an Easter table covering the years 532 up to and including 721. Dionysius' table was published in 525 and only a century later accepted by the church of Rome, which from the third century up till then had given preference to go on using her own, relatively inadequate, Easter tables. From about the middle of the seventh century all controversy between Alexandria and Rome as to the correct date of Easter ceased, as both churches were now using identical tables.
Bartholomew MacCarthy was a scholar and chronologist who wrote extensively on Early Irish literature.
An ecclesiastical full moon is formally the 14th day of the ecclesiastical lunar month in an ecclesiastical lunar calendar. The ecclesiastical lunar calendar spans the year with lunar months of 30 and 29 days which are intended to approximate the observed phases of the Moon. Since a true synodic month has a length that can vary from about 29.27 to 29.83 days, the moment of astronomical opposition tends to be roughly 14.75 days after the previous conjunction of the Sun and Moon. The ecclesiastical full moons of the Gregorian lunar calendar tend to agree with the dates of astronomical opposition, referred to a day beginning at midnight at 0 degrees longitude, to within a day or so. However, the astronomical opposition happens at a single moment for the entire Earth: The hour and day at which the opposition is measured as having taken place will vary with longitude. In the ecclesiastical calendar, the 14th day of the lunar month, reckoned in local time, is considered the day of the full moon at each longitude.
Augustalis was the first bishop of Toulon, according to some authorities. He was appointed in 441. He attended the Council of Orange that year, and the Council of Vaison the following. He is associated with the civitas of Arles by the Martyrologium Hieronymianum, which honors him on September 7. He is also named by the Martyrologium romanum on that day, with his location noted as in Gallia. An Augustalis, most likely this man, appears among a group of bishops addressed by Pope Leo I in letters dated 22 August 449 and 5 May 450, the latter of which addresses issues of jurisdiction between Arles and Vienne.
Aristobulus of Alexandria also called Aristobulus the Peripatetic and once believed to be Aristobulus of Paneas, was a Hellenistic Jewish philosopher of the Peripatetic school, though he also used Platonic and Pythagorean concepts. Like his successor, Philo, he attempted to fuse ideas in the Hebrew Scriptures with those in Greek thought.
